How to find the motivation to quit when you haven't yet faced any consequences due to your drinking?

I know how ridiculous this sounds but how do you quit when you're high functioning and not physically dependant? I know logically that I can't keep this up but it's like my brain can't accept that I need to quit when right now it feels like I'd be throwing away the key to solving all of my problems. At the same time it has become a huge source of shame as I hide all of my drinking and feel powerless to stop. I know it is just a crutch that will end up exacerbating all of my issues but I'd like to quit before this happens. Just can't seem to find the motivation to do so, would love to hear any advice from someone who has been in a similar spot. Thanks in advance
